Question

1. Place the following compounds in order of decreasing strength of intermolecular forces:

F2 NH2CH3   CH4

2. Put the following in order of decreasing boiling point:

N2   NO   H2O

3. Which of the following defines a critical point?

a. The point above which liquid and gas look the same

b. The temperature at which the soild and liquid coexist

c. The point below which liquid can not exist

d. The temperature at which the boiling point equals the meltling point

e. The temperature and pressure where liquid, solid, and gas are equally stable and are in equilibrium.

Explanation / Answer

Answer:

1) The decreasing order of strength of intermolecular forces is NH2CH3>CH4>F2.

2) H2O>NO>N2 the order of decreasing boiling point.

3) The temperature and pressure where liquid, solid,and gas are equally stable and are in equilibrium.
